Helping someone with a very different worldview

Hi everyone, I have always wondered on how to support people with very different beliefs whether they are in a cult or having psychosis, or having severe anxiety that alters reality so I did some readings. I would like to share with everyone my findings. 

The underrated approach

Avoid mirroring the person’s own body language. It can make them even more paranoid because sometimes it comes off as a personal attack when they are already nervous or defensive. The more aggressive they are, the more you have to remain calm as much as possible to ground them. Don't overreact too. This will create a comforting presence. Speak simply and clearly to the point so they don't get the wrong idea as they are constantly reading between the lines. If they refuse help, allow them space and don't provoke them. Try not to do things that cause more suspicions like whispering or being very shocked around them.

General

Avoid stigmatizing, mocking, patronizing or criticizing. Do focus on understanding.

Ideal Interaction

Do be a safe and neutral person for them to confide. This will help them feel less alone. Listen to them patiently without confronting nor confirming their beliefs. Focus on their emotions and empathize. I have read that specialists said confronting with their beliefs can come across as being against them unknowingly. The strong, fundamentally different worldview they have can't be broken easily. I understand there might be frustrations when they are talking about things that seems bizarre. Yet, It's not intentional because they can't see the bigger picture.

I seek everyone's help to make the world an inclusive and non-threatening place. Thanks for reading.
